hi i am trying to set up my efis to a bendix mag , we get a signal but it is erratic , all gain , filter and ballast are off , also my oil pressure does not read , it is a vdo sensor what settings should i have .cheers RRR

on further investigation can hi and lo are wired correctly, how ever the resistors that were given to me are 56 k ohm not 120 ,so i am oredering new ones as we speak , also does the rdan have to be earthed at the 9 pin as well as the earh slot on the right hand side of the rdac .thanks

i will check i may have typo error but thanks

i wired the across the 2 can hi lo wires at each end

i have rwo resistors , one at each end in the 9 pin d sub the ar 12 kohms

hi , getting frustrated and annoyed , i have in stalled a dicovery lit and rdac , power to both systems is good, rdac has a pulsating green light, both 9 pin plugs have resistors in them and voltage at efis end is showing 3 volts. problem is the efis is showing red x on all engine and radio displays...
